Abstract
Die Erfindung bezieht sich auf eine Drehzahlerfassungseinrichtung (20, 40, 52, 54, 58) für eine Aufladeeinrichtung (10), insbesondere für ein Laufrad (12) eines Verdichterteiles eines Abgasturboladers mit einem Gehäuse (30). Diesem ist eine Sensorschaltung (20) sowie mindestens ein Permanentmagnet (20, 52, 54) und mindestens ein magnetoresistives Element (58) zur Erfassung eines wechselnden Magnetfeldes zugeordnet. Das Gehäuse (30) ist aus Kunststoffmaterial gefertigt und in eine Wand (32) des Gehäuses (30) sind mindestens ein Permanentmagnet (52, 54) und die Sensorschaltung (20) räumlich getrennt voneinander angeordnet.
